Spikesarefast,shortdurationelectricaltransientsinvoltage(voltagespikes),current(currentspikes),ortransferredenergy(energy spikes) in an electrical circuit. Voltage spikes usually happen when the AC/DC adapter is plugged in, or charge currentiscutoffquickly.Multivoltagechargersareconstructedusingtransformersthatmaybecapableofproducingspikesthat exceed the maximum ratings of the Rolls LFP battery. You must ensure that the charger being supplied: •Meetstherecommendedchargecurve •IncapableofexceedingRollsspecifiedmaximumterminalvoltages

7.3 Charge Curve

1. Charge at constant current to 3.4 V per cell module (Bulk). 2.Maintainconstantvoltage3.4Vpercellmodule(Absorption). 3. Terminate when charge current drops below 2A. 4. Optional Float at 3.35V per cell module (Float).

Always make sure the chargers charging curve meets the battery’s charging requirement; never charge a visibly damaged battery; never charge a frozen

battery.

Do not charge battery higher than 3.4 V per cell module.

Recommended charge current is 0.5C

Do not discharge battery below recommended minimum operating voltages.

Do not store a discharged battery. Recharge battery after every use. Batteries that have self-discharged to a

severely discharge state are not recoverable.

Do not discharge battery at rates greater than recommended operating currents.
